Create, revise, migrate, or audit portable Agent Skills packages. Use when the user requests skill authoring or explicitly invokes this skill to review instructions, structure, or portability.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Creating Portable Skills Produce an installable package that does the user's reusable job and follows the [Agent Skills specification](https://agentskills.io/specification), with useful evaluation cases and a grading method built through the upstream workflow. For a read-only audit, apply [references/review-checklist.md](references/review-checklist.md) and return prioritized findings with file evidence and a verdict. For authorized creation, revision, or migration, use the workflow below. Existing authorization and the host project's constraints carry forward. ## Author the package Ground the skill in the user's intent, existing package, representative inputs and outputs, and corrections from real work. Identify the outcome and hard constraints that make completion acceptable. Check the host's contribution rules, discovery path, and existing owners before adding a workflow or helper. For a new skill, use [assets/skill-template.md](assets/skill-template.md). For a revision, the last commit can preserve the prior version. For a migration, revise a copy and preserve the source. Read [references/portability.md](references/portability.md) when choosing frontmatter, …

How to install
mdr add jrgilbertson/the-rookery/creating-portable-skills@sha256:6c84041f50eafa21The line at the top of this page pins the label git:20261003.135e2af, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
